7 Claims.

Clothes wringers are commonly provided with what is known as a dripboard. This drip board deflects the water as it is expelled from theclothes and deflects it so as to carry it on to a water board. In orderthat the water may be deflected in either direction, the drip board isusually pivotally mounted. Usually these reversible drip boards havebeen made with a plane flat base and different methods of assembling, orsuporting the drip board have been provided. The present invention isdesigned to improve the drip board both as to function and as tocheapness of manufacture. Features and details of the invention willappear from the specification and 1 claims.

A preferred embodiment of the invention is illustrated in theaccompanying drawing as follows;

Fig. 1 shows a front elevation of a wringer,

20' partly in section.

Fig. 2 an enlarged sectional view on the line 22 in Fig. 1.

Fig. 3 a section on the line 33 in Fig. 2.

The wringer frame, as shown, is made of pressed metal having a base 1,stiles 2, and top bar 3. It is provided with rolls 4, 4 operating in theusual manner. A water board 5 is provided with up-turned side flanges 6and a seating portion 7 at the center. The seating portion is providedwith a slot 8, preferably of key-hole shape adapted to register with asimilar shaped slot 9 in the base. The water board is secured in placeon the base by a bolt 10, the head of the bolt being passed through thelarger part of the slot and brought into the smaller part for assembly.

An opening 11 is formed at the centers of the flanges 6. This opening ispreferably struck up forming a lip 12 around the opening so as to form 1a bearing surface. The drip board 13 has a base portion 14 and endflanges 15. Trunnions 16 are struck up and formed at the center of theflanges 15. The metal is given a cylindrical shape so as to fit thebearing opening 11 in the end flanges. In assembling the drip board theend flanges are sprung apart sufficiently to receive the trunnions 16.

It will be noted that the base portion 14 is formed with upwardlyinclined sides, that is to say, the portion at one side is inclined tothe portion at the opposite side, giving to the structure as a whole asomewhat trough shape. This has two very important advantages, first itstiffens the drip board and consequently makes it possible to form it ofmuch lighter metal than 1931, Serial No. 521,433

where a straight plate is used, and, it increases the inclination of theup-turned portion of the drip board so that as the water reaches it, itis more definitely deflected back toward the tub than with the lessinclination of the flat drip board. It is practical, therefore, to bringthe edge of the drip board slightly closer to the center without dangerof spillage over the edge. This permits of rolling the edge of the dripboard, as at 1'7. This assists in stiffening the board and presenting asmoother surface as to any clothes that may reach it. Preferably thewater board has shoulders 5a which the turned edges 17 overlap at thelower edge of the drip board. Thus a more effective screen against theoutflow of water is accomplished.

The drip board is provided with a downwardly extending projection 18 atits center which engages an ordinary spring 19 secured to the waterboard. The effect of the spring is to yieldingly hold the drip board inadjustment when swung to either position. Here again the inclination ofthe sides of the bottom portion to each other and consequent stiffeningof the metal makes the placing of the spring at the center morepractical in that the stiffness of the drip board readily sustains thetension of the spring.

A shoulder 5a is provided in the drip board and the rolled edge 17extends downwardly below this shoulder, thus more definitely preventingthe passage of water from one side to the other of the wringer.

What I claim as new is:-

1. In a wringer, the combination of a frame; rolls mounted in the frame;and a pivotally mounted drip board under the rolls, the base po tion ofthe board having upwardly inclined sides with downwardly turned edges,said board having upwardly turned end flanges and pivotal mountings forthe board on the end flanges.

2. In a wringer, the combination of a frame; rolls mounted in the frame;a pivotally mounted drip board under the rolls, the base portion of theboard having end flanges with trunnions extending integrally incontinuation of the walls of the flanges and forming pivotal supportsfor the board; and a spring yieldingly holding the board in adjustment,said spring exerting pressure on the trunnions.

3. In a wringer, the combination of a frame; rolls mounted in the frame;a water board mounted in the frame, said water board having flexible endflanges with bearing perforations therein; and a drip board having endflanges with trun- I nions extending integrally in continuation of thewalls of the flanges, said trunnions extending into the bearingperforations.

4. In a wringer, the combination of a frame; rolls mounted in the frame;a Water board mounted in the frame, said water board having flexible endflanges with bearing perforations therein; a drip board having endflanges with trunnions extending integrally in continuation of the wallsof the flanges, said trunnions extending into the bearing perforations;a downward projection at the center of the drip board; and a springmounted on the water board operating against said projection yieldinglyholding the drip board in adjustment.

5. In a wringer, the combination of a frame; rolls mounted in the frame;and a pivotally mounted drip board under the rolls, said drip boardhaving end flanges with trunnions extending integrally in continuationof the walls of the flanges and forming pivotal supports for the board.

6. In a wringer, the combination of a frame; rolls mounted in the frame;a water board mounted in the frame, said water board having end flanges;a drip board having end flanges adjacent to the end flanges of the waterboard; and pivotal connections supporting the drip board, said pivotalconnections being arranged between the flanges on the drip board and theflanges on the water board, said pivotal connections comprising pivotalmembers telescopically arranged one within the other, one of the flangesbeing resilient and permitting the separation of the flanges forassembling the pivotal members.

7. In a wringer the combination of a frame; rolls mounted in the frame;a water board mounted in the frame; a drip board pivotally mounted onthe water board, said boards having end flanges, and one pair of flangesbeing provided with integrally formed trunnions on the flanges and theother pair of flanges having integral bearing surfaces receiving thetrunnions.
